AI Insight
An international team led by the University of Oxford has discovered two extremely low-density giant planets classified as "super-puffs," with densities lower than cotton candy (candy floss). These planets represent some of the least dense giant planets ever detected. The findings were published in Monthly Notices of the Royal Astronomical Society through a collaboration involving researchers from the University of Oxford, Université Côte d'Azur/Observatoire de la Côte d'Azur, and the University of Birmingham.
Why it matters
These unusual planets challenge existing models of planetary formation and evolution, as their extremely low densities are difficult to explain with current theories. Understanding super-puff planets could provide crucial insights into atmospheric composition, planetary migration patterns, and the diversity of planetary systems beyond our solar system.
Understand the Science
An international collaboration has discovered two of the lowest-density giant planets ever detected: rare “super-puff” planets with densities lower than candy floss. The study—led by the University of Oxford, in collaboration with Université Côte d’Azur/Observatoire de la Côte d’Azur and the University of Birmingham—has been published in Monthly Notices of the Royal Astronomical Society.
